| 摘要: |
| 大停电事故后送电路径的恢复是电力系统恢复过程中的一项重要任务，合理的送电路径及其充电方式将有助于系统安全、快速恢复。结合理论分析与仿真给出了典型参数下线路的极限充电距离；针对给定的送电路径提出了线路分组投运方式以缩短系统恢复时间，建立了以分组数量最少为目标的整数线性规划模型，同时针对某一恢复路径存在多个分组投运方案的情况，定义了恢复可靠性指标对分组方案进行优选。为了给运行人员提供多个备选路径方案，建立了基于网络流理论的前K条送电路径优化的整数线性规划模型。采用高效的商业优化软件联合求解前K条路径优化模型与线路分组投运模型，获得前K个最优路径方案及其分组投运方案。算例结果验证了合理的线路分组充电方案能够在保证恢复安全性的前提下加快系统的恢复进程。 |

| Abstract: |
| The restoration path of transmission line after a major blackout is an important task in the restoration process of power system, and reasonable restoration path and charging mode will help the system to recover quickly and safely. Combined with the theoretical analysis and simulation, the limit charging distance of the transmission line under typical parameters is given. Aiming at the given restoration path, the method of line restoration in groups is proposed to shorten the system’s recovery time, and the integer linear programming model is established with the least number of groups as its objective. At the same time, the recovery reliability index is defined to optimize the grouping scheme when a certain restoration path has multiple line restoration schemes. In order to provide multiple alternative path schemes for operators, an integer linear programming model of the first K optimal restoration paths based on the network flow theory is established. Efficient commercial optimization software is used to jointly solve the optimization model of first K paths and the model of line restoration in groups to obtain the first K optimal path schemes and their grouping operation schemes. The results of an example show that a reasonable line charging scheme can speed up the system recovery process on the premise of ensuring the recovery safety. |
